Study on the frequency profile modeling technology of the MMW radar seeker

It is difficult to realize the high range resolution for the target in powerful ocean clutter,so the frequency profile modeling technology is proposed,which can get the high resolution information of the target in frequency domain.The precondition of the frequency profile modeling is first analyzed and the factors impacting on the profile modeling ability are given with the simulation results.Then the acceleration impaction on the frequency spectrum is given and the acceleration channel compensational algorithm is proposed.Finally,the acceleration compensational precision is given.
